MW7675B Large Format Planar Grinding Equipment
Facilities processing oversized circular metal components require grinding hardware built to accommodate wide diameter and thick stock dimensions. Many standard grinding units come with limited horizontal travel and insufficient spindle power, which means operators must split large batches into smaller groups and re-fixture parts repeatedly. This extra handling creates minor dimensional shifts and slows overall line throughput for high-volume production runs.
This Big Surface Grinding Machine is sized to match production workflows focused on large blanks. Its 900mm reciprocating travel length reduces fixture repositioning during batch processing, while paired high-output spindle motors deliver consistent cutting force for deep stock removal on thick metal workpieces. The machine's wide working envelope covers a broad range of large-diameter circular parts, with structural elements designed to dampen vibration generated during full-load grinding cycles.
All core mechanical assemblies are sized around heavy, wide-format workpieces. The layout prioritizes stable long-run accuracy without sacrificing operational flexibility for mixed-size batch schedules common in heavy manufacturing workshops.
Machining Precision Benchmarks
All tolerance readings are recorded under continuous full-load operation. Minor deviations may appear based on workpiece material hardness and blank geometry:
- Parallelism deviation: 0.008 mm
- Flatness tolerance: 0.008 mm
- Inter-batch thickness variance: 0.02 mm
- Finished surface roughness: Ra 0.63 μm
Consistent planar tolerances support reliable assembly for heavy-duty mechanical components such as large bearing races, mining equipment flanges and construction machinery disc parts. Uniform finished surfaces distribute mechanical load evenly once installed, cutting down uneven wear during equipment service cycles.
Core Specifications and Functional Advantages
Wide Machining Envelope for Oversized Circular Stock
The machine's working range is calibrated for large-format circular blanks typical in heavy industry:
- Processable workpiece diameter: Φ150 mm to Φ500 mm
- Supported workpiece thickness: 10 mm to 150 mm
A Φ750mm standard grinding wheel provides a broad contact surface for full-face grinding on wide blanks. The large abrasive disc maintains steady stock removal rates across the full diameter of workpieces, reducing the frequency of wheel dressing maintenance during extended production shifts. The 130mm vertical grinding head stroke delivers ample vertical clearance to fit tall fixtures and accommodate maximum-thickness 150mm workpieces, streamlining changeovers between thin and heavy blanks.
Long Reciprocating Travel and Fixed Calibrated Spindle Speed
The 900mm horizontal reciprocating travel length is a key design feature for large batch processing. Multiple large-diameter blanks can be secured in a single fixture setup and processed through one continuous grinding pass, eliminating repeated alignment steps that introduce dimensional inconsistency. The spindle runs at a fixed 770 RPM, a rotational speed calibrated for thick, high-density metal blanks. This steady rotation delivers consistent grinding texture across wide workpiece surfaces, supporting reliable semi-finishing results without surface irregularities.
Dual High-Power Spindle Motor Configuration
Two 30kW spindle motors operate in tandem to deliver balanced cutting torque during heavy-load grinding. This dual power layout evenly disperses operational vibration across the machine base, preventing spindle deflection that would degrade flatness accuracy during multi-hour production runs. The combined power output handles deep stock removal on thick alloy and carbon steel blanks without motor overload, extending the service life of core drive assemblies for daily continuous workshop operation.
Suitable Production Segments
This large-size grinding unit fits heavy bearing manufacturing plants, construction machinery component workshops, mining equipment foundries and heavy vehicle parts fabrication facilities. It is used for batch planar grinding of thick, wide-diameter circular metal blanks, cutting fixture adjustment downtime and improving finished component qualification rates for high-volume production lines.
Frequently Asked Questions
Q1: What production benefits come with the 900mm reciprocating stroke?
A: The extended horizontal travel enables processing of multiple large-diameter workpieces in one clamping setup. It cuts manual repositioning work and limits human-induced dimensional errors during batch processing.
Q2: Is this machine built for non-stop heavy batch production?
A: The dual 30kW spindle motor setup and long-stroke reinforced frame suppress operational vibration during extended shifts. The unit maintains stable dimensional consistency through back-to-back production runs, matching the throughput demands of heavy manufacturing facilities.
